FILLING MECHANISM.

T0 ZZ whoml t may concern.'

Be it known that I, Anonrii GRONLUND, a citizen ot the United States, residing at Stockholm, in the countyv ot Aroostook and State ot Maine, have invented certain new and usetul improvements in Filling Mechanism, ot which thc 'following is a specilication, reference being had to the accompanying drawings.

This invention relates to Filling mechzv nisms and has 'tor an important object there of the provision of' a device whereby solid materials may be deposited in a pluralitiT ci receptacles, the discharge into each receptacle being discontinued when the receptacle has received a predetermined amount.

A turther object of the invention is to provide a device of this character wherein the materials placed in 'the receptacles are positively directed into the receptacle. i

i still further obj ect ot the invention is to provide a chute for delivering materials vto a plurality of receptacles, the chute embodyinnr tiltable sections arranged over each receptacle or series of receptacles which tilt when the first series oit receptacles hasheen filled to cause the delivery ot the material trom the chute into a second set o't receptacles.

Further objects Vot the invention will ap. pear as the following specific description is read in connection with the acompanvmg` drawings which Jform a part ot this application and in which Figure 1 is a si le elevation with the inner side plate removed so as to more clearlyv show the arrangement of the parts. the parts being shown in elevation;

Figure 2 is a similar view taken from the opposite side ol the machine with the inner side plates attached; Figure Vis a section taken onthe `line of Figure l:

Figure 4 is a similar view taken'on the line 4-,4 of Figure l;

Figure 5 is a section-taken on the line 5-5 of Figure l; and Y Figure Gis a detail longitudinal section showing the method ot' tripping. the platform sections. Y. i

Referring more particularly to the drawing` 1 and 2 'represent side bars which are connected together by the' bottom 3 and which have rising therefrom the uprights 4,` 5, 6 and 7 to which are attached the side plates S, 9 and 10. 'Y

vbearings 17 in the side bars land 2, and

have secured thereto the collars 18' between which and thebracing bracket. I9 is lo cated a spiral spring 20 which takes up anv shocks but permits rotation of the shaft 41,6; as the machine is turned to Vfollow' the digger. n i

Extending across the machine and jour; naled in the uprights 5 is a shaft 2l havin V secured at opposite ends thereof thesprocket wheels 22 which areconnected .to similar sprocket wheels '23 on the shaft l2 bv al sprocket chain 24. The shaft 21 also lhas secured thereto sprocket wheels 25'arranged at opposite ends' and connected bv means 'ot the sprocket chain 26 to the sprocket wheels 2T secured upon the. crank shaft 2S. the purpose o't which will be hereinatter described. Atene side of the machine the shatt21 has secured theretoa 'pulley 2 9 connected b v a cross belt 30 to a similar mille).7 3l arranged upon one end of ashaitt 32 journaledY in bearings upon an extension 33'which projects lmriaontally1 from adjacent the outer ends Qt the uprights 4.` n Y, 'i l Y l` "lhesha-tt 32 carries sprocket wheels which are connected by means'ot theA chains to similar sprocket wheels 36 ke'ved. to al sha'tt 37 which is journaled .in bearings upon the under side of, the side bars lk adjacent their forward end. .These chains carrv suitable transverselj.T disposed nights or convehvorrbuckets 38 which, when loaded.v rest upon thesupporting boardk 89-inclined from the upperV surface ot the side bars 1Y to thevr vextension 33. vAt the .forward yendA ot the side bars l I provide a transverselyl extending scoop or receiver member 4Q adapted to receive the potatoes from the dlggenl'as will belliereinafter4 more tullv understood,

the ilights'or buckwhich is connected to similar cranks 42 on a shaft 43 `Which is journaled in bearings carried by brackets 44 mounted-lonithe aprig'hts 4c by a bar45. VThese bars, as shown, are

rounded upon their upper face'and flat upon their lower face and by the action of the cranks are" caused not "only to reciprocatew y bars 45' drop upon a screen 49 which is` plvoted tothe uprights 6, as at. and has its opposite endeconnected to the crank 5 1. formedlonvthe shaft 2l.

a substantially leif'el. portion 52 'and an ,in-i

' clined portion 53. The screen 4:9 is provided,

Vto separate all smalllpotatoes from the large potatoes and` in order tojsavei these small potatoes which y are passed through the screen, I provi-dean inclined chute-5a arrangedinnnediately `belowtl-ie screen and between the uprights and 6 and adapted to direct `the small potatoes into af box., or Vother container removably positioned between` theuprights 4` and 5. The large potatoes which areeyidiseharged bythe screen 53 fall upon a platforln which is secured rearwardly of` thel u rights between the side bars 57 connect tothe upperends of the uprights 6 and 7 atthesides of the machine, as shown` in Figure 5"." Extending across and secured to sha-tts 58 journaled in the side., bars 57 are platform--` sections, 59,l eac-h of which is provided with oppositely disposed segments 6()` secured to the' ends of the platl forni seetions,`as shown in Figure l, Each of the segments 60 is proyidedfwitli an in` Wardlyextending studl atene side of the shaft 58 of its associated section, and piroted to the side plate-lllimrnediatelybeneath the stud of each section is a `latchin l lever 62 having an offset and dependingenc which. enters 'a barrel 64. to belilled. The upper A end ofthe latehing leveris proifided .with

a hook adapted to :engage oyer thestud and1holdthe section 59 1nhor1zontal position. Iloreachrseglnent I secure to the Vside plate "n10, atonegend, a contractile. spring. 66, A

Whoseopposite end "is 'connected'totlie segmenton "thefopposite side of .the `shaft 5 8 from thestud, so fthatwhe'n the hook 65 isfreleased from thestud,` the` spring" willjact to throw the section to y a `Vertical position, as

i indicated in Figure `1.

Journeled in suitable bearings on-thennderfside of `thesda bars l, at :separated l This screen is shghtly angularA 1n cross'lsection so that1 when 1n its uppermost position 1t will have points, are the shafts 67 and 68,V each of which carries sprockets 69' connected to-` gether bychainsfTO' on opposite sides of the machine.v The shaft 67 also carries a sprocket 7l which is in turn connected by achain 72 to an operating sprocket Z3 jour nailedlu ion a stub shaft 74 and 'curr ino a' crank 75. Each of the shafts 67 and 63 carries, intermediate the side bars l, suitable rollers or drums 76 upon which lisniountedj aV slatted conveyor 77 `preferablyV resting upon or sliding over the bottoni 3, as will be readily understood. rAny suitable anti-fric tion nieans,`not shown", inay be interposed betweentheslats ofthe conveyor-'and the bottom in ordery to insure free operation ofV .the.conveyor.` Allfbarrels to be filled are mounted upon the conveyor,` as shown .in

Figures -l and 5, and :the rows ofi barrels may `containasrnany asis rfound desirable in` practice, the two end* or side barrels each having the offset or depending ends 6B of the levers 62 placed therein so that when lthe potatoes beingr `discharged `into `the. barrel fill the saine,` theyiwill contact with the ends '63, throwing tlreni to the position shown in dotted lines inFigure 6,-and releasing the hooks `65 from `the studs and permitting` the spring `66 to-throw the section tothe position shown ein, dotted lines in .Figure 6, Which prevents any more potatoes being' discharged into the end roW of the barrels. The sectional platform thenterminates at the end of the adjacent section 59, andthe potatoes are `discharged .fronr the endiof said sec-V tion into the next row of barrels Where the operation is repeated.v When all of the barrels have been lilledthe machine is stopped and the operator turns the crank toward hiru which moves all of the barrels outwardly. `The bottoni of the machine is `of a height equal to the height ofthe bed of a Wagon so that the barrels may be discharged rightl on to the Wagon bed and `then conveyed away;` After all the filled'barrels have been removed, new einptybarrels are placed in 4.position on the conveyor, and by rotating the .handle away-` from. the operator, `may 'be placed in proper position :beneath the scc tions, it being understood of course that the latch Alevers are turned out of the Way Afirst to permit their proper entrance` into the barrels whenthe barrels are properlyr positioned beneath the sections. A y

VFrom the foregoing it is thought thatfthe operation` of the machine will bev readily understood.- I, however, desireto state Athat the digger employedl may be any vsuitable type, ,and'is so connected tothe machinethat it Will `dump the potatoes onto the .member 40 fromy which' they are Vpicked upy by the liights or buckets 38 of thewconiveyor, and then conveyed,`asrhas been previously de-l scribed, to the shaking bars 45 over theplatform 46. It Will. thus be seenthat Iliayeprw vided a machine which will take the potatoes from the digger and separate therefrom all stones .and soil and then sort the small potatoes from the large potatoes, after which the machine Will automatically till a plurality of barrels carried thereon, and as each set of barrels is lilled, will automatically act to cut oil the supply to that set of barrels and discharge the potatoes into another set.

That I claim iS:

l. l filling mechanism comprising a plurality of pivoted sections independently shittable about the pivots thereoif to Combine With the remaining sections to form a s. chute for delivering material or a batlie checking the flow or" material along the chute formed by the remaining sections, and means ior moving each of said sections to the last named position operable when a predetermined amount ot material has passed thereovcr.

2. A [illing mechanism comprising a plularity of pivoted sections independently shirt'table about the pivots thereof to combine nith the remaining sections to form a chute for delivering material or a bale checking the flow or material along the chute formed by the remaining sections, means for moving each of said sections to I the last named position, and material releasable means for locking the sections engaging each of said sections and tending to move the same to the last named position, and a latch locking each section against movement under the inluence of its spring and Withdrawn by the engagement of the material therewith when a predetermined amount of material has passed over the section.

4. A filling chute comprising a plurality of independently tiltable sections, each section when tilted forming a, baie limiting the movement of'material passin over the discharge end of the chute, and means rendered operative by the passing of a predetermined amount of material over the discharge end of the chute for tilting the section forming the discharge end to form a battle.

In testimony whereof I hereunto atlix my signature.
